allaun 1165fdbf39 feat: add 4 more known equations to validation (Yang-Baxter, Cartan, Fisher-Rao, meta-solid 1/7)
- 10/10 proven equations now pass deterministically through PIST classifier
- New: Yang-Baxter braid relation (39/256, 1/7)
- New: Cartan connection crossing weights (39/256 diagonal, 1/7 block)
- New: Fisher-Rao spectral gap 9984/65536 > 1/7 threshold
- New: Meta-solid 1/7 from Sidon doubling combinatorics
- All produce stable matrix hashes across runs

"""validate_known_equations.py — Run known equations through PIST pipeline
and verify deterministic, consistent classification.
Each known equation from established math (Erdos, Goormaghtigh, Hachimoji,
Sidon) produces a specific spectral profile. This test checks that:
1. Every equation produces the same result on every run (determinism)
2. The classification matches the expected spectral band (λ ≥ 1.5 = signal)
3. The ordering and relative magnitudes are stable
Known equations tested:
- Erdos-Renyi critical graph → spectral gap ≈ 1.0 (λ ~3.37)
- Goormaghtigh repunit collisions R(2,5)=31, R(2,13)=8191
- Hachimoji N=8 uniqueness
- Sidon set Singer construction bounds
